Question

Give examples of

• A negative feedback control mechanism

A positive feedback control mechanism

Answer 1

Homeostasis is derived from the Greek words for "same" and "steady," and it refers to any process that living things use to actively maintain fairly stable conditions necessary for survival. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is maintained by negative feedback loops within the organism. Homeostasis is controlled by the nervous and endocrine systems in mammals.

Negative feedback mechanisms examples include the regulation of blood glucose levels and osmoregulation, and thermoregulation. Some examples of positive feedback mechanisms are contractions in child birth, Ovulation, Blood clotting, and Lactation.
